An 88-year-old woman had been followed for several decades in our Movement Disorders Clinic for very long lasting Parkinsonism. In November 1918, while she was still nursing at age 3 months-old, she and her mother were infected by epidemic encephalitis. Before the age of 10, dystonic postures of the lower limb occurred and progressively worsened, leading to orthopedic deformities. When she was 19, after her first pregnancy, a resting tremor appeared in the left hand. Akinesia and mild hypertonia occurred several years later, with partial improvement during the pregnancies. Her Parkinsonism worsened very slowly and after World War II she was confined to wheelchair. Her Parkinsonism improved with the introduction of levodopa, but severe adverse effects including choreic peak-dose dyskinesia and dystonic movements occurred 3 years later. Mild psychiatric disorders appeared in the long term, along with obsessive compulsive disorders. In 1994, 70 years after the onset of extrapyramidal signs, global cognitive function assessed by the Mattis Dementia Rating Scale was normal for age: 138/144. Brain MRI was normal. 18Fluro-Dopa PET demonstrated a severe bilateral and symmetrical reduction in fluoro-dopa uptake which was more marked in the putamen than in the caudate. Fluctuant cognitive decline significantly occurred at the age of 87, with hallucinations. She finally died at the age of 88 years old.


The brain and the spinal cord were obtained by autopsy. The right hemisphere and samples from brainstem and cerebellum were deep frozen for biochemical analysis. The left hemisphere, the spinal cord and most of the brainstem and the cerebellum were fixed in 10% buffered formalin. Gross examination showed mild atrophy of the temporal lobe (Figure 1) and the subthalamic nucleus, as well as loss of pigment in the substantia nigra (Figure 2). Microscopic examination showed moderate spongiosis and neuronal loss in the substantia nigra (Figure 3) and locus coeruleus, but no Lewy bodies were seen. Rare plaques were observed in the temporal and occipital cortex. Tau immunohistochemistry (using AD2, a monoclonal antibody raised against the phosphorylated serine residues 396-404 of tau) revealed sparse neurofibrillary tangles in the locus coeruleus (Figure 4) and the substantia nigra. The same lesions were more numerous and associated with threads in the subthalamic nucleus (Figure 5), the zona incerta, and hypothalamus. Neurofibrillary tangles, neuropil threads and some neuritic plaques were present in the entorhinal cortex, hippocampus and inferior temporal isocortex, but absent in frontal and parietal areas. Rare tau-positive tufted astrocytes were also observed in the putamen (Figure 6), the pallidum, and the cerebellar white matter. Alpha-synuclein immunostaining was negative. Brain homogenates containing 20 micrograms of total proteins from the temporal cortex (BA38), frontal cortex (BA10), primary motor area (BA4), parietal cortex (BA39), occipital cortex (BA18), hippocampus, pallidum, putamen, thalamus, subthalamic nucleus, mesencephalon and the medulla oblongata were loaded on SDS-PAGE. Hyperphosphorylated Tau proteins were detected using AD2 antibody. We observed a pathological Tau triplet at 60, 64 and 69 kDa in the hippocampus, the temporal cortex, putamen, subthalamic nucleus, medulla oblongata and lightly in the pallidum, thalamus and mesencephalon (Figure 7).
